| Abstract |
Need for multidisciplinary validation in aeronautics: There is a strategic interest in Europe for designing new safer, quieter and cleaner products in Aeronautics and Aerospace industries meeting society's needs and ensuring competitiveness. The affordable in time and cost product designed in an industrial multidisciplinary environment requires confident knowledge of the quality of main codes used in design. Despite recent advances in modeling, experimental and computational methodologies there is still a lack of confidence in the coupling and integration of affordable industrial software for multidisciplinary analysis and design.
The gap of technology for multidisciplinary design in aeronautics requires new models and software taking into account multi physics and multi-scale coupling effects. Methodologies in design have also to adjust to new interactions between specialists in different disciplines in a concurrent engineering procedure.
Multidisciplinary Validation requires knowledge of modelisation, experimental and numerical limits. A considerable effort at the European level has to be organized for surveying and collecting experimental, theoretical and numerical data originating from several disciplines as a necessary step towards proposing new methods and procedures.
Projects aims
The aim of the PROMUVAL AM are prospective studies to prepare the future for emerging validation procedures for the solution of multidisciplinary problems in aeronautics. The starting data originates from ongoing European network projects such as FLOWnet, QNET and MACSINET providing computational and experimental knowledge database tools and well web-documented CFD test cases of a single discipline.
The coupled disciplines to be considered include fluids, structures, chemistry and thermal flows with applications in aeroelasticity (flutter and fatigue), aero/vibroacoustics (noise), aeroheating (anti-icing), combustion (pollution) and turbulence (noise), among others. New experiments and modern diagnostics measurement techniques will be prospected and identified for future rigorous multi-disciplinary validation purposes. The critical multidisciplinary aeronautic problems to be considered for validation include:
- Multi scale/multidiscipline study of vortex hazards at transonic regime (safer),
- Multi scale/multidiscipline study of bang hazards (quieter),
- Flutter validation for a large variation of mass loading (safer),
- Reduction of combustion contribution to pollutants spreading (cleaner) ,
- Interaction in supersonic and hypersonics between large structures in turbulent boundary layers and wall for aeroelasticity, oxydation, acoustics,…(safer, cleaner and quieter),
- Reduction of buffet generated by separation by MEMS technologies (safer).
Project partners
PROMUVAL partners are recognized experts from Aeronautic and Aerospace industries (AIRBUS, Alenia, Dassault Aviation,EADS Germany and SNECMA), Research Organizations (CIMNE, INRIA, CIRA, DLR, ONERA and CENAERO) and University (NTUA, UMIST, Univ. Rome and VUB). The partnership includes two major European Scientific Associations: the European Research Community on Flow Turbulence (ERCOFTAC) to bring its expertise in the set up of new guidelines for Multidisciplinary Data Quality Assessment as well as their contribution to dissemination activities and the European Community on Computational Methods in Applied Sciences (ECCOMAS). All partners will provide expertize modelling, experimentation and simulation through joint prospective activities, a Short Course and a Workshop to define a roadmap with guidelines to validate affordable industrial multidisciplinary numerical and experimental tools for advanced design.
Key milestones: The PROMUVAL milestones are:
- Collection and dissemination of existing data on physical and mathematical models, experimental and numerical methods and test cases using existing database tools and a web-based communication system.
- Identification of critical RTD areas in multidisciplinary analysis and validation.
- Specification of a future pilot software platform for multidisciplinary analysis in aeronautics.
The outcomes of PROMUVAL will contribute to the engagement of industry to reduce noise, damaging emissions and to increase safety by monitoring automated systems to react immediately to hazards.
A better level of understanding of coupled Physics, Modelling European and Numerics for affordable multidisciplinary validation will help undoubtedly and significantly the task of aerospace industry in producing the competitive products needed in the first two decades of the 21st century. |
